Sumiko Premier MMT Arm VTA?


I have an AR ES–1 TT with a Sumiko Premier MMT arm with a Sure V–15V MR cartridge which is a good match with no VTA adjustment needed. This arm has no VTA adjustment but I have been told there is a conversion kit for my arm to upgrade to a VTA adjustable unit.Is this so and where can I get one? I might want to change cartridge types and would probably need to adjust the VTA. If not what are my options?(shims) Any suggestions or contact information would be helpful.Thanks

If it has no VTA adjustment, and you don't want to get another arm, then you have only one option, and that is to make machined spacers that will fit between the arm board and the base, that will be the correct thickness to raise the VTA to the proper level for that cartridge. This really allows only one VTA because it is too difficult to keep changing these for small variations in record thickness.
If the new cartridge has too much VTA, then you can use spacers that are available to fit between the cartridge and the headshell.

I suppose also you could use a spacer disc under the record mat,or different thicknesses of record mats to do the same thing as the headshell spacers, if the TT allows this.
